1.Blue Carbon products use lithium iron phosphate batteries, the depth of discharge can reach 80%, and the depth of discharge of lead-acid batteries does not exceed 50%. which means 25-50% more usable capacity compared to the same size lead-acid battery, but typically 1/3 weight. 2.The circuit is designed so that the charging current will not exceed 0.2C, which ensures normal operation
even under the climate conditions of Hailar (minimum daily average temperature -27°C).
